Abstract

Procédé d'électrodialyse avec membrane bipolaire (BP) pour la régénération d'acides selon lequel on réalise entre une électrode positive (anode) et une électrode négative (cathode) une succession de compartiments base B, acide A, sel S, déterminés par une succession de membranes cationique, bipolaire, anionique, cationique, bipolaire, etc..., une circulation de solution ayant lieu dans chaque compartiment. On applique contre la face anionique (11) de la membrane bipolaire (BP), une membrane anionique supplémentaire (10), sans laisser d'écart mesurable entre les deux membranes, de manière à réduire la contamination du compartiment acide par des cations.
